I don't want a static list of these options: I want the user to be
able to modify them.  I want to have the defaults to be sane (I may
add a few common options) but allow advanced and/or slow use cases
(like coverage generation) to be added by the user.

In retrospect, I think I can do this by munging sys.argv before
setup() is called, but I am wondering if that is among the better
ways.  It seems rather heavyhanded for setuptools to insist to be
informed a-priori of every single valid option, so I imagine there may
be another way.
